The term "Year One" in political history usually refers to the institution of radical, revolutionary change. This usage dates from the time of the
French Revolution. After the official
abolition of the French monarchy on 21 September 1792, the
National Convention instituted the new
French Revolutionary Calendar. It declared the day after abolition – 22 September, redesignated as 1
Vendémiaire – to be the first day of
the Republic and the beginning of Year I.
